What is a small housing development?
A small housing development is a scheme of a few new homes, typically two to nine, on a single site. We work with landowners, small developers and investors to build schemes that already have planning permission, or help take a site through planning first.
How much does a small housing development cost in Keynsham?
In Keynsham, a small housing development typically costs £1,850–£2,750 per m² of floor area (build cost), including VAT at 0% (zero-rated for qualifying new dwellings). For a typical 400 m² project that is roughly £740,000–£1,100,000. Building costs in the South West are close to the UK average, so the figures for Keynsham are close to our national guide. Design, structural calculations and council fees are extra.

Do you need planning permission for a small housing development in Keynsham?
Approvals for a small housing development in Keynsham follow the rules for England. In England small schemes need full planning permission and may involve a section 106 agreement, the Community Infrastructure Levy, highways and drainage approvals, and biodiversity net gain where it applies.
Building regulations approval comes from the council’s building control service or a registered building control approver. The work is inspected at key stages, such as foundations, drainage and insulation, and a completion certificate is issued at the end.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.

From survey to sign-off, the job normally involves:
- Warranty and building control inspections

How long does it take?
The build itself usually takes 12 to 24 months depending on scheme size. Allow time beforehand for drawings and approvals, usually 6 to 12 months.
